Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524932, here are decompositions:

139 + 31524793 = 31524932
211 + 31524721 = 31524932
409 + 31524523 = 31524932
433 + 31524499 = 31524932
463 + 31524469 = 31524932
601 + 31524331 = 31524932
631 + 31524301 = 31524932
661 + 31524271 = 31524932

Showing the first eight; more decompositions exist.
